Freeze Frame Data can be helpful in duplicating and diagnosing adaptive fuel concerns. This data (a snapshot of certain PID values, recorded at time DTC was stored in Continuous Memory) is helpful to determine how vehicle was being driven when fault occurred, and can be especially useful on intermittent concerns. Freeze Frame Data, in many cases, can help to isolate possible areas of concern as well as rule out others. See FREEZE FRAME DATA MODE for a more detailed description of this data.
